FORT WORTH, Texas — A coroner says the passenger killed while riding a Texas roller coaster was ejected from her seat and plummeted about 75 feet before striking a metal beam.

The Tarrant County Medical Examiner's Office released additional details Tuesday on the death of 52-year-old Rosa Irene Ayala-Gaona. She was found dead Friday night at the Six Flags Over Texas amusement park in suburban Dallas.

The official cause of death remains pending, but the office says the Dallas woman's body was found atop a ride tunnel for the 14-story Texas Giant roller coaster.

The coroner says Ayala-Gaona was ejected from her third-row seat as the ride began a steep descent along the track's first large hill.

An autopsy showed she suffered multiple traumatic injuries and extensive trauma to her torso.
